Have you done any work to the carburetor?Sounds like the carb. is dirty and needs to be cleaned. you may also need a carb. kit, depending on how old it is. If you need further assistance on how to do this, feel free to ask.

I installed new carb. on my tecumseh 5hp. snow king and it wont start. I have spark and gas is flowing out of carb.

This can be very frustrating and tough on the back and arm.
Always confirm the the fuel tank valve is open and the stop/run switch is in run position

It takes three things to run:
  1. Compression. This is the resistance that you feel as you crank the engine. Some engines have compression release to assist getting the rotation started. You should be able to feel the compression stroke as you rotate, Remove the plug and you can easily tell the deference. If it had, last time used, been running and starting with no problem I would assume that the compression is OK. Gauges are available to check. at lease 120 PSI
  2. Spark. It is near impossible to lose the spark timing on these. It can only be magnitude and presence. If in doubt about the condition of spark plug replace. I usually lay the plug on top of the head with wire attached and observe for the spark. No spark no start.
  3. Confirm that the throttle is in the wide open position. It is possible during the repair the spring or rod has closed the throttle air valve. Air/fuel mixture is always hard to trouble shoot. I use open choke and starter fluid to conform that compression and spark are working. After that I will choke on a cold motor and pull listening for the first fire. At the first fire I would usually half choke and pull to first run. Full choke for many pulls will only flood engine!! If no joy then I would allow engine to vent and go back to start fluid. If it will run on start fluid than either carburetor is messed up or quality of fuel is bad.
If after several tries and fuel is certain to be good remove plug and check for gas. It is possible that the new carb float valve or mixture adjustment screws are messed up.

Has spark fuel and 125 compression will not start?

Use a small amount of starter fluid in the intake past the filter. If the engine fires than you can be confident it is a carburetor problem.

Check for water in the gas

The carb cleaner may not be volatile enough to support ignition. The over the counter starter fluid is easily ignited even in cold weather.
If the engine has been in storage with old gas it is likely that residue has formed in the carburetor. If it does fire up with stater fluid but will not run with full choke it will most likely require a carburetor cleaning.

1992 suzuki 750 it's got spark but won't start, what could it be?

engines require three things, spark-at the right moment, fuel, and compression. If you're sure you have a strong and consistent spark, move on to your fuel. Drain everything you can and start with fresh NON OXYGENATED (no alcohol) fuel. In recent years 1/2 the troubles I see is from poor quality fuel. I spray a shot of starting fluid into the airbox and if the bike starts or at least coughs that tells me I have a fuel problem. Last but not least perform a compression test. The psi isn't as important as each cylinder should be with 7lbs of the rest.
After an attempt to start, pull the plugs, are they wet or dry? If wet crank the engine over for 20-25 seconds with the plugs out and re attempt a start choke off and a light shot of starting fluid. Give this a look and report back your results. Good luck

I have a 2001 3.0 ford taurus compression on all cylinders less than 90 psi

The car should start, even with low compression in some cylinders. Since two things are needed for combustion, fuel and spark, you need to figure out which is the problem. Remove a spark plug (or buy a spark tester from harbor freight) and check for spark at the plug. Without a tester, simply attach the plug wire to the plug while removed from the engine and rest the base of the plug on the engine block (grounding it). Have someone turn the engine over with the key and observe if you see a hot spark jumping the gap of the plug.
Recommend you go to the library and borrow a copy of Chilton's for your car model.

Engine wont start it is getting spark and fuel any other reason why it won't start

You need 3 things for an engine to run; spark, fuel and compression. How is the compression? Is the spark plug new? If the plug is old, it could give a nice spark when you check it but have no spark under compression. Make sure the fuel you're using is fresh. If you give it a small shot of starting fluid and it fires up, your fuel delivery is suspect. In that case, you will need to remove the carb an THOROUGHLY clean it paying close attention to jets and passages. I always give people this warning: when cleaning jets and passages, NEVER use steel instruments. Use wood, copper wire or other materials that are softer than the material you're working on or you run the risk of ruining jets or even the entire carburetor.

My stihl fs 350 wont start at all any sugestions ?, thanks from mark uk

I would have a shop do a compression test on the engine. It should be at least 100 psi to run. And then a spark test on the ignition module to see if it firing to the spark plug. I would look at a carburetor rebuild. I would also mix up some fresh fuel mixture; anything over 30 days now is considered bad gas.
